Anyway, the caption explains: “The microscopic behavior of a carbon nanotube with a tear resembles somewhat the motion of a ladybug. The rip in the nanotube fabric, caused by heating stressing the nanotube, is sewn up in a moving process in which carbon a pentagon-heptagon structure propagates along the tube.”

Huh? I mean, I think I understand what’s happening, but what does it have to do with ladybugs? I mean, any more than it does an amoeba or something? Cute picture; unhelpful analogy.

I kinda like the filmstrip holes indicating the passage of time, but I wonder how biased that is toward people of a certain age. Do they use film in classes any more? Have most kids seen a movie projector, let alone an actual strip of film?
